SAFETY GUN TRIGGER Filed March 26, 1957 Z4 1 2g 5 L 6 INVENTOR 1. MEAf). A/mmsm 17/5 ATTORNEY This invention relates to a safety guntriggenand has for one of its objects the production of a simple andStates atent eflicient means for positively locking the trigger of a gunagainst movement, and thereby preventing the accidental discharge of thegun, the parts of the device being easy to assemble.

A further object of this invention is the production of a simple andefiicient means for limiting the forward movement of the pull or pushrod, so as to prevent the safety lock from wedging too tight.

Another object of the invention is the production of a simple andefficient latching means for the pull or push rod which will insure ofinstantaneous and positive release of the latching means and engagementwith the pull or push rod when the push buttons are actuated, these pushbuttons being relatively long to facilitate gripping thereof by the handof an operator particularly while wearing mittens and the like.

Other objects and advantages of the present invention viill appearthroughout the following specification and am.

This application is an improvement on my Patent No. 2,380,140, issuedJuly 10, 1945, relating to Safety Gun Trigger.

In the drawing:

Figure l is a fragmentary top plan view of a portion of a gun, showingthe safety means located thereon;

Figure 2 is a horizontal longitudinal sectional view showing the partsin a locked position;

Figure 3 is a view similar to Figure 2, showing the parts in a releasedposition;

Figure 4 is an irregular transverse sectional view taken on line 44 ofFigure 2;

Figure 5 is an end elevational view of the trigger lock;

Figure 6 is an enlarged side elevational view of the trigger lock, aportion of the trigger also being shown;

Figure 7 is a detail perspective View of the latching dog or pawl, forlocking and unlocking the pull or push rod;

Figure 8 is a fragmentary side elevational view of the inner end of thepush or pull rod;

Figure 9 is a perspective view of one of the operating push or pullbuttons.

The present invention constitutes an improvement over my previous PatentNumber 2,380,140, issued July 10, 1945, and relating to a Safety GunTrigger.

By referring to the drawing, it will be seen that 10 designates thestock of the gun, which carries the conventional barrel 11. The stock 10of the gun is provided near its forward end with a pocket 12, in whichis mounted a box 13. A button-receiving socket 14 is formed in one sideof the stock 10 and communicates with the pocket 12. A button-receivingsocket 15 is formed in the opposite side of the stock 10, and alsocommunicates with the pocket 12. The socket 14 is in offset alignmentwith the socket 15. An elongated push-button 16 is mounted within thesocket 14 and an elongated pushbutton 17 is mounted in the socket 15.These pushbuttons 16 and 17 are elongated to facilitate pping thereof bythe hand of an operator, particularly while wearing mittens and thelike. A plunger rod 18 is carried by the push-button 16 and supports apivot link 19. A spring 20 is interposed between the push-button 16 andthe box 13 to normally urge the button 16 outwardly. This button 16 ispreferably provided with a suitable flange 21 to limit the outwardmovement of the button 16. A similar spring 22 is carried by the button17 and this button 17 is constructed similarly to the button 16.

The push-button 17 is provided with a plunger rod 23, and the plungerrod 23 extends into the box 13 for engaging and locking the pull or pushrod 24 in a safety position in a manner described in the following. Asis shown in Figures 2 and 3, the plunger rod 18 extends into the box 13in an opposite direction to the plunger rod 23 and transversely of thebox 13. When operated, the plunger rod 18 shifts the push rod 24longitudinally to release the plate 32 from a locking position relativeto the trigger 39-see Figure 6. t

The pull rod 24 extends longitudinally of the stock 10, and carries anexpansion spring 25 at its forward end, the spring 25 being located inthe socket 26, which extends longitudinally of the forward end of thestock 10.

The spring 25 is adapted to normally pull the pull rod 24 forwardly andthis forward pull is limited by means of the stop 27 which abuts againstthe box 13, as is shown in Figure 2. The link 19 which is pivotallyconnected to the rod 18 is also pivotally connected to the pull or pushrod 24 and is inclined rearwardly and away from the push-button 16, asis shown in Figures 2 and 3. The rod 24 is provided with a transverselyextending toothreceiving notch 28 in spaced relation to the link 19, andthis notch 28 is adapted to receive the toothed end 29 of the dog orpawl 30. The dog or pawl 30 is pivotally mounted upon the transverselymoving plunger rod 23, is bodily movable away from said pull or push rod24, and is provided with a rearwardly extending fulcrum finger 31, whichextends into a suitable aperture formed in the stationary rear end ofthe box 13 constituting an abutment for said finger 31. The notch 28 isadapted to receive the toothed end 29 of the dog or pawl 30 for thepurpose of holding or locking the pull or push rod 24 in a set position.The dog or pawl 30 is moved out of engagement with the notch 28 bypushing inwardly on the button 17 to permit longitudinal movement of thepull or push rod 24 when the button 16 is operated. As the dog or pawlis bodily moved away from the pull or push rod 24 it is simultaneouslyswung upon its pivot to swing the toothed end 29 out of the notch 28.

The rod 24 is provided with a knob 33 at its rear end, in front of whichknob 33 is fitted a hook 34 of the trigger releasing and engaging slideplate 32. The rod 24 is provided with a shank 35 near the knob 33 forthe purpose of receiving the hook 34. This hook 34 is carried by theforward end of the plate 32 and this plate 32 is provided with a pair oflongitudinally extending slots 36 for receiving the retaining screws 37.The screws 37 are adapted to secure the plate 32 to the conventionalbolt of the gun 38 shown in dotted lines in Figure 6. The plate 32 isprovided at its rear end with a depending lip 40 which is adapted toengage the shoulder portion 41 of the trigger 39 and hold the triggeragainst movement until the lip 40 and the plate 32 are shifted to adesired position.

The operation of the device is as follows:

The parts are normally in the position shown in Figures 2 and 6. When itis desired to fire the gun, the left hand of the operator will engagethe forward portion of the stock 10 adjacent the push-buttons 16 and 17with his right hand and trigger finger adjacent the trigger 39. Thepush-button 17 is then pushed inwardly, thereby re- Patented Feb. 3,1959 tion shown. in Figure 6, where the depending. lip 40*.will

be moved. out oi engagement with the shoulder 410i the trigger 39. Thismovement will permit the trigger 39 to be swung for releasing the firingpin of the gun.

It should be understood that. the present. device may be applied tovarious types of firearms, and only those portions of the gun which areessential to all types have been illustrated, in view of the fact thatthe present invention relates to a means for locking the trigger againstswinging movement until the. trigger is first mechanically releasedbythe operation of the pushbuttons 16 and 1'7. As shown in Figure 6, thetrigger 39 is pivoted, as at 42',

and it should be understood that, the bolt, the particular said pull rodfor normally holding the pull rod in a safety position, a pull rodactuating member engaging the pull rod for shifting the pull rod whensaid locking member is released from said pull rod, the locking memberand the actuating member being mounted adjacent said pull rod andextending at right angles to said pull rod, said locking and actuatingmembers being located forwardly of said trigger and releasing plate, anelongated depressible push-button, mounted upon each side of said gun,one push-button being connected to said releasable locking member andthe other push-button being connected to said pull rod actuating member,the elongated pushbuttons facilitating operation of the push-buttonswhile the operator is using hand coverings, such as mittens and thelike, said pull rod having a notch, and said releasable locking membercomprising a dog, a plunger rod, said dog being pivotally mounted uponsaid plunger to bodily move said dog away from said pull rod, said doghaving a rearwardlyextending fulcrum finger, and an abutment forengaging said finger to simultaneously swing said dog out of said notchas said dog is bodily moved away from saidpull rod.
